A man who fucks bicycles is on the loose in Sweden. After Swedish cyclist Per Edstrom had his bike violated one too many times, he installed a security camera in front of his home, left his bike outside, and then waited.

Sure enough, the hooded bicycle lover showed up, cut open a tire, and began to masturbate onto the bike as the tire deflated, all while holding a piece of paper in his hand.

"My girlfriend finds it all a little concerning, you never know if he has checked her out in some way, and whether it is a picture of her he has in his hand when he is masturbating," Edstrom told the Swedish paper Kvällsposten.

Not that he's worried. "This man is probably completely harmless, bicycles are just his thing," said Edström. "I am not scared of him, but mostly irritated over all the punctures I have had to fix."

Somewhat unbelievably, this is not the first time there's been a bicycle-related sex scandal in Sweden. In 2007, a 35-year-old man was arrested and convicted of masturbating onto at least 20 bikes around Stockholm.
